Metering Modes and Hyperfocal Distance

Ok, so I'm probably getting pretty geeky now so I'm assuming that if you actually clicked on this post then you are ready to geek out with me.  So, my last post was about the concept of hyperfocal distance and how to use that with back button focus.  My wife, daughter and I went to Beiteddine the other day and had the chance to fool around with metering modes.

I had watched a tutorial that suggested that photographers stick to either center-weighted metering or spot metering modes depending on whether they were in a controlled environment or shooting on the go.  I decided to test this theory out the other other day.

Since I was "on the go" while walking around Beiteddine, I selected center-weighted metering mode, put my 17mm f4.0 to 17mm and f8.0 and set the focus to the hyperfocal distance.  I think proceeded to walk around the Beitedding complex taking some shots.  I kept the in mind the fact that anything closer than about 4ft (125cm) would be out of focus.  I then set my other two back buttons to start metering and lock metering.  I was able to quickly set and lock metering by touching the two aforementioned buttons quickly in sequence and then move to the trigger to take the photo.  This system, combined with the hyperfocal theory, help produce fast and reliable results as I walked around.  Here are some examples.

Hyperfocal Distance, Back Button Focus and Byblos

With our most recent visit to Lebanon, I had a chance to play around with hyperfocal distance.  Ever since I started to consider getting into underwater video, I've been fascinated by the this theory.

To oversimplify a complicated theory, hyperfocal distance is the focal distance at which you set your camera for a given aperture and focal length in order to achieve the maximum depth of field.  It will extend from a certain point in front of the camera until infinity.  The advantage of this theory is that as long as everything in your picture is more than the minimum distance then everything should be in focus.   There are a glut of apps out there that will help you calculate your hyperfocal distance.  Just simply search for "hyperfocal" and you will find them. This approach is incredibly helpful when working with underwater video as it allows you to set your focus and simply concentrate on recording and framing and not dealing with focusing knobs etc.

During our last trip to Byblos, I decided to play around with this theory and apply it to photography.  I set my camera to f11 and my focal distance to 0.8m.  This meant that everything from 0.3m to infinity would remain in focus as I took pictures.  Since my camera was set to back button focus and manual mode I simply had to pull the shutter release button.  I found it a easy and effect way of taking photos that kept everything in focus while giving you complete control over your exposure.  I would think that this would be effective in a situation where there is limited change in light.  Variable light would require a much more complicated approach.  In any case, here are some samples from the day.

Beirut - Lebanon

Yesterday, I attempted to return to my camera again for Photowalk purposes.  I led the Beirut leg of Scott Kelby Worldwide Photowalk through the streets of this lovely city.  Mostly made up of friends and colleagues, we meandered through the tight alleyways and busy roads while attempting to capture images that represented the street life of the city.  It was an interesting process.  During other photowalks, I was able to zone out and get into my grove by disappearing into the background of the group.  By leading this walk, I found myself involved in some great conversations and I got to know quite a few interesting and fun people but I found it hard to really get into the grove of taking pictures.  I guess this really helped reinforce that photowalks really are about the social nature of photography.  Perhaps I've been missing something during all the other walks that I had been taking.  Here are a few of the images that I captured during the walk ...

Bavaria - The Land of Castles and Churches

Wow, how long has it been?  Well, hopefully this is me starting up again.  Having a baby and updating her blog has taken my photography focus elsewhere recently.  I did get to play around with some HDR photography in the churches of Bavaria over our Spring Break.

The photos of the churches were taken hand held, then auto-aligned in Photoshop.  Afterwards, I used Photoshop to process the HDR images and then pulled the resulting file into Lightroom for final editing.  I'm starting to learn more about exporting photos from Lightroom into smaller file sizes.  I've realized that the histogram can really be  your friend in this situation.  After much trial and error, I now know that it is important for me to pull the shadows up out of the left quarter of the histogram to get an exposure that I like.  In these images I used a combination of the shadows slider and exposure slider to accomplish this.

The photo of Neushwanstein was a straight up 24-70 f2.8II shot at around 40mm/f8.0.  I pulled the blues and overall highlights down to get the darkened sky.
